The Overall Score in Driving Behaviour is a percentage-based rating that averages all activated driving parameters, like ECO speed, idling, and harsh braking, using weighted values. It helps identify the most and least efficient drivers or vehicles, showing fleet performance at a glance.

The score is color-coded from A (best) to G (worst), making it easy to monitor. This rating helps improve safety, save fuel, and reduce emissions by providing useful feedback on driving habits.
